Presentation of the Boulogne-Billancourt school

In Boulogne-Billancourt, 123 mon école opened its doors in September 2021.

Ideally located, the kindergarten is both spacious, with 387 square metres, and very bright.

The children are welcomed in a fully bilingual environment, English/French.

Starting school at the age of two helps to build confidence and independence and prepares children for kindergarten.

The pedagogical foundation is based on Montessori materials, carefully selected to support the global development of 2 year olds. Other activities, such as plastic arts, hip-hop, musical awakening and baking, complete the program.

Life at 123 mon école


At 123 mon école, lunch is a continuation of the Montessori approach to education, rather than an interruption. Mealtime is an opportunity for children to share and learn the rules and customs of living together with grace and courtesy.


Nap Time

Nap time is for all children in pre-school and first grade.
Organized from 12:30 to 3:00 pm, the children can take the time they need to rest.
Each child has a year-round bed in the nap room, with a sheet and blanket provided by the school.

Toilet Learning

Most toddlers have not yet learned to use the toilet on their own. Our teachers care for them during diaper changes and guide them gradually towards independent toilet use.

The goal is for them to be out of diapers by the time they enter primary school.

Everyone needs time to adjust

Each school year, children integrate into the school day gradually, at their own pace.

A private recreation area

The school has a large, 100m² inner courtyard with safety flooring and playground equipment.

On the first floor, the terraces will be used for gardening.

Field Trips

Get out of the school, go on a group outing, live the adventure!
Every year we organize outings for the children of the school.
This is an opportunity for them to discover all sorts of fun and cultural activities.
For example, in previous years we went to the Aquarium, the Jardin des Plantes, the Musée en herbe, the Farm, the Jardin d'acclimatation and the theater.



For the pleasure of bringing our team, parents and children together, we organize several parties: one for Halloween, one for Christmas and one at the end of the year.
Each year we offer new shows and fun; puppet shows, a cotton candy stand, balloon sculpting and much more to discover!
